8. A guarantee method of a stage performance personnel safety guarantee system based on GPRS technology is realized based on the stage performance personnel safety guarantee system based on the GPRS technology in any one of claims 1-7, and is characterized in that: the method comprises the following specific steps:
the method comprises the following steps: infrared rays emitted by a first infrared emitter (3) on the fixed block (2) are received by a first infrared receiver (4), a rectangular area is defined by the edge of the top end of the lifting stage (1), and then the infrared rays are transmitted to a first controller (25) through an A/D converter and then transmitted to a computer (18) through a first Bluetooth module (26);
step two: a performer wears the positioning assembly (19) on the body through a waistband (34) and an elastic clamp (35), then stands on a lifting plate (9) on the lifting stage (1), the weight of the performer presses the lifting plate (9) downwards, the lifting plate (9) touches a first pressure sensor (11), the first pressure sensor (11) transmits a signal to a first controller (25) through an A/D converter, and the first controller (25) starts an electric push rod (7) so that a rectangular frame (6) moves upwards to extend out of the top end of the lifting stage (1) and surround the steps of the performer;
step three: the second infrared emitter (32) and the second infrared receiver (33) on the rectangular frame (6) are positioned at the top end of the lifting stage (1), infrared rays emitted by the second infrared emitter (32) are received by the second infrared receiver (33), so that a rectangular safety area is defined inside the rectangular frame (6), then the second infrared receiver (33) and the second infrared emitter (32) transmit signals to the first controller (25) through the A/D converter, and then the signals are transmitted to the computer (18) through the first Bluetooth module (26), at the moment, the performers are positioned in the safety area, and the area outside the rectangular frame (6) and the edge of the lifting stage (1) is a dangerous area;
step four: a performer puts feet into the elastic bandage (12), the heel of the performer steps on the second pressure sensor (17) to trigger the second pressure sensor (17), the second pressure sensor (17) transmits a signal to the first controller (25), the first controller (25) starts the double-shaft motor (15), the pull rope (13) is wound on an output shaft of the zigzag-shaped groove (5) to tighten the elastic bandage (12), and the elastic bandage (12) fixes the feet of the performer;
step five: the position information of the personnel can be transmitted to a computer (18) through a GPRS personal locator (22), a second controller (21) and a second Bluetooth module (23), so that the personnel can know that the performance personnel are in a safe area all the time;
step six: when the performer needs to move on the lifting stage (1), the performer releases the second pressure sensor (17), the first controller (25) enables the double-shaft motor (15) to rotate reversely to open the elastic binding band (12), the performer can move on the lifting plate (9), when feet of the performer move to the edge of the rectangular frame (6), the feet of the performer block infrared rays of a pair of the second infrared ray emitter (32) and the second infrared ray receiver (33), the first controller (25) transmits signals to the computer (18), the computer (18) transmits the signals to the second controller (21), the second controller (21) controls the micro vibration motor (24) to work to enable the shell (20) to vibrate to remind the performer, and the performer immediately feels that the vibration moves to a safe area in the center of the lifting stage (1).
